All of the fragrance oils I use in my candles are free from phthalates, and do not contain any materials with similar health concerns, including those on California’s Prop 65 list. Materials known to be carcinogens in California aren’t any safer elsewhere! My candles are free from the following: ✖ Carcinogens: These are materials known or thought to cause cancer. ✖ Mutagens: Materials that change the DNA of a cell, harming the cell and causing diseases like cancer. ✖ Reproductive toxins: Toxins that adversely affect reproductive organs and increase the risk of birth defects. ✖ Organ toxins: These are toxins that can cause adverse effects or disease within specific bodily organs. ✖ Acute toxins: Toxins that can cause adverse effects from a single exposure. Generally, this would be accidental exposure like spillage or ingestion.
